COVER FOB. BOXES AND THE LIKE.

Application med October 26, 1923.

This invention relates to a cover for boxes and the like of the type having a sight opening through the cover by means of which the contents of the box may be seen and a glass 6 covering the sieht opening.

One of the objects of the invention is to provide a cover of the above-mentioned t 'pe in which the glass may be easily and quickly removed or put in place and when once l in 1place will be securely held there.

t is customary in covers of this type to provide a name plate carrying advertisements. etc., and the name plates are usually held in position by the glass with the result that if the glass breaks or becomes loose the name plate falls out of position. It is a further object of the invention, therefore, to removably fasten the name plate to the cover independently of the glass so that should the glass become broken or be removed the name plate-will remain fixed in place.

Another object of the invention is to construct a. oover in which. the glass is removably held in osition to cover the sieht opening by shou ders formed on, the llange of the cover to engage one side of the glass and movable tabs struck upfrom the material of the cover to removably engage the other side of the glass;

A further object of the invention is to so position the glass and the glass holding tabs that the tabs will not be broken even though they are bent back and ,fortha considerable number of times when changing glasses.

Other objects and features of the invention will more fully a pear from-the f'ollowing description a the accompanying drawings and will be particularly pointed out in the claims.

The drawings illustrate in perspective, elevation and section a preferred form of. construction of a cover for a box and embody the broad principles of the invention.

In the drawings:

Fig. 1 is a. front elevation of the cover;

Fig. 2 is a section on line 2 2. Fig. 1;

Fig. 3 is an enlarged perspective of the glass held in position by the glass holding tabs;

Fig. 4 is an enlarged section on line 4-l., Fig. l;

Fig. 5 is a reduced elevation of the nameplate separated from the cover;

Fig. 6 is a section on line 643. Fig. 1;

Serial No. 870.868.

Fig. 7 is a detail showing the position of the parts when the glass is being inserted.

As illustrated herein 1 designates a box which may be of any `suitable construction.

I`he cover of the present invention cornprises a rim portion 2 which fits over the sides of the box 1 and is removable therefrom, and a cover port-ion 3 hinged to the rtm at 4. The cover is provided with a sight openinv 5 surrounded by a ledge 6 under which ies a pane of glass 7 to close the opening. A flange 8 depends from the circumference of the ledge to roperly space the cover from the rim Q. rom the rim portion 2 a flange 9 extends inwardly over the edge of the box and an inner flan e 10 rises from the flange 9 and is bent ack upon itself to give a smooth edge in order that a person who is removing the contents of the box will not injure himself.

The present invention has to do with novel means for retaining the glass in a position covering the sight opening and means for holding the name plate 11 on the cover independently of the glass. In order. to hold the glass in position, glass retaining shoulders 12 are struck up from the flange 8 to engage one side of the glass and glass retaining .tabs 13 are struck up from the material of therledge o posite the shoulders to removably engage the other side of the glass whereby the glass may be held against theledgeand cover the sight opening.

The glass retaining tabs 13 are so positioned with re ard to the edge of the glass that the tabs will not be broken even though they arebent back and forth a considerable number` of times when changing the glass. In order to accomplish this the side cuts 14 through the ledge from which the tabs are strucky up extend under the glass and toward the si ht opening such a distance that when the g ass is in place and the ends 15 of the tabs are bent over the edge .of the glass, the tabs are rolled into a smooth curve, as distinctly shown in full lines in Fig. 4. The glass is of such a size that the edge 16 thereof over which the tabs are bent extends partially over the tabs and thus there is no distinct bending line across the tabs so that when the tabs are opened into the position shown in dottedlines in Fig. 4, for the re.- moval of the glass, the curve on which the tabs are bent merely enlarges. The entire! tab does not swing as on a hinge about a line across the tab as would be the case if thc glass did not extend partially over the tab. It is well known that if metal is bent a few times along a line it will break at the line but if the metal is rolled into a smooth curve it may be unrolled quite a considerable number of times before there is any tendency for the metal to break. Thus by forming the tabs into a smooth curve and inserting the glass under the end of the tab, when the end of the tab is bent down over the glass and bent up again, the tab simply unrolls and there is no bending line along which the tab could break.

The shoulders 12 are struck up from the flange 8 as shown in Figs. 1 and 2 with the edge 17 farthest from the flange pressin against the glass. By using shoulders struc up from the flange and tabs struck up from the ledge to hold the glass in lace the cover can be made very easily and c eaply because the sight opening and the shoulders and the tabs are all formed in one o eration.

The shoulders are refera l positioned with relation to the glass as s own in the drawings. When the shoulders are struck up from the flange 8, openings 18 are necessarily formed in the flange. 'When the glass is in position as shown in Fi 2 the glass covers the openings 18 there y preventing any dust or dirt from entering the box.

It will be seen that in order to allow the tabs to roll into a. smooth curve and to prevent a. bending line forming across the tabs it is desirable to space the glass slightly from the ledge. To keep the glass spaced from the ledge, the inner edge 19 of the ledge is bent downwardly into such a position that said edge presses firmly against the glass when it is in pro er osition. With the arts thus arranged t e g ass is prevented rom rattling and is firmly secured in position covering the sight opening. As shown in Fig. 7 when t e glass is placed in the cover, the edge 20 of the lass is inserted between the ledge 6 an the ed 17 of the shoulders with the edge 16 of t glass spaced from the tabs. Then the lass is brought into the final position w 'ch causes the front of the lass to press against the inner edge 19 of t e ledge 6 throughout its entire length. The en'ds of the tabs are then bent over the edge 16 of the lass and the glass is firmly secured in p ace. Rattling and looseness of the glass is prevented because the inner edge 19 of the ledge 6 bears against the front surface of the glass and the shoulders 12 and the ends of the tabs bear against the rear surface of the glass. The cover is referably made of a ductile material which as some spring o it and when it is stamped out the inner edge 19 is bent down slig tly more than is necessary so that when thc glass is in final position the edge 19 is pressing against tle glass with sufficient force to prevent any P al* The name plate 11 is held on the iinp`roved cover independently of the glass.

or this purpose slits Q1 are cut on the ledge 6, preferabliv at the time the cover is stamped out, and the name plate is provided with tongues 22 which project through the slits and are flattened against the under side ofthe ledge. To give a neat appearing box the slits 21 are so placed that when the name plate is fastened on the ledge 6 it is positioned directly over the openings 23 formed by the cutting of the tabs in order to hide the openings. Although only one name plate has been shown it is obvious that any number may be used and positioned anywhere desired on the ledge. The cover is preferably designed as shown in Fig. 1 with the sight opening a little to one side thereby leaving a name plate holding ledge 24 of substantial Width at one side of the sight opening.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:
